[ 150/221] iwlwifi: fix PCIe interrupt handle return value

[Greg Kroah-Hartman]

3.7-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Johannes Berg <johannes.berg@xxxxxxxxx>

commit 392d4cad7907f6cb4ffc85e135a01abfddc89027 upstream.

By accident, commit eb6476441bc2fecf6232a87d0313a85f8e3da7f4
("iwlwifi: protect use_ict with irq_lock") changed the return
value of the iwl_pcie_isr() function in case it handles an
interrupt -- it now returns IRQ_NONE instead of IRQ_HANDLED.

Put back the correct return value.
